SKIN REFINING CLAY MASK Skin Refining Mask deeply purifies and refines the skin with noticeable results after just one treatment. Mineral rich clays normalise sebum production, minimises the appearance of pore size and revitalises lackluster skin. Lactic Acid gently dissolves dead skin cells whilst mineral clays remove unwanted toxins from the skin for a more purified, refined skin that looks brighter and refreshed.
